Okay.. I know this has been stated and restated, but I got a lame example..
(Ex. So Jimmy (lame name) admits that he is gay.. (lol.. coming out the closet..)
Chances are that Jimmy (lame name) may of seemed to "decide" to be gay, but why turn gay for no reason? Why would one go gay when they're bound to get ridiculed, perescuted, and maybe even disowned by their parents. Maybe, it's because he's getting more turned on by that guy over there than that female elsewhere in the room. Now, if one was wired normally, their mindset wouldn't go that way (like straight people like us), but if some part of his genetic code malfunctions or "malfunctions" (the "" obviously are depending on how you view gays..) and makes the hormones flow more when he sees his own sex.. ah.. forget it..
My point is that like so many have stated and restated, if you don't think it's possible to be born to become gay, you're wrong.. very wrong.. We have all sorts of other ways our genes can be screwed up or malfunction, whether from birth or the environment. Why can't being gay be one of them? So, in most cases (if not all of them), I personally think that it's not Jimmy's fault that he's attracted to his own sex.. it's the way his genes were wired or as in most of the general public's view, ill wired..
Another opinion of mine and the main reason I posted.. is that I also think that it is possible to "decide" to go gay, based on a really bad break-up or series of bitter break-ups.. I mean.. seriously.. how do you think this is going to affect a person's trust of the opposite sex? If there's no trust in the opposite sex anymore, then how are they going to love them again? Sure, this is probably remedy-able, but what if it doesn't get remedied immediatey? This is another cause that I do believe people would be complete dumbasses (lol.. here's another genetic defect.. and a solid one, if that..) to deny.
Anyways, like it's been said before, if people can be born retarded/ with Down's Syndrome or any one of the various genetic conditions (like the disease that makes kids age too fast or that.. damn it.. I forgot what it's called, but it screws up your lungs.. Cystic.. Fibrois?), where their body's are wired to either make them retarded, screw up their organs, or screw up their mind, then how can they not be wired to be gay? Oh wait.. wouldn't being gay be similar to your state of mind being screwed up? (Not that I feel that way towards gays, but still..)
